She makes motherhood look effortless, combining it with her career as a model, TV host, producer and businesswoman — but Heidi insists being mom to four kids is the hardest job of the lot!

How do ‘Project Runway’ host Heidi Klum and husband Seal manage full time careers and a houseful of kids? A lot of hard work and the best-behaved children in the world!

“They all have different likes and dislikes and activities that they want to do. You have to learn how to juggle all of that, and at the same time, give them each the love that they need,” Heidi tells US Weekly.

“When you have one (child), you can focus on one. With four, you have to make sure (your attention) is all spread out just right,” she says. “You have to understand how different they all are! And at the end of the day, there is not much time left for you!”

Leni, Henry, Johan, and Lou range in age from 22 months to 7 years old — but Heidi insists they’re the best of friends and a “united” bunch!

“They always stick together and take care of each other,” she says, “They love each other! They love helping Lou (the youngest). They like to feed her (and) they include her in all their activities.”

How cute!

We think you’re doing a great job parenting Heidi! What do you think HollyMoms?
